Create JDBC realm on glassfish - wrong pass? - jdbc

Question

I've followed this tutorial http://blog.gamatam.com/2009/11/jdbc-realm-setup-with-glassfish-v3.html
The problem is that I get login dialog again and again like pass is wrong (and never page), but I clearly see values in DB. Pass is MD5 of the word 'admin'.
So how to debug it?
Here are the settings and printscreens: http://codepad.org/jHNRpAta
